The North Pole is the coldest place in the world. So cold that only Santa Claus, Mrs. Claus and his merry toy making elves can live there.
But not too far south there are some people who brave the winter weather to make a warm home for themselves and for their families.
And it's there, as legend has it, that the last lonely lighthouse points the way home for Santa every Christmas Eve as he makes his way around the world, delivering gifts to all children who have been good.
Like most lighthouses, the one just off the coast of Christmas Town is tended by a kindly old man and his small family all throughout the year. For a long time now, Santa's lighthouse keeper has climbed the spiral staircase to the top of his lighthouse and lovingly wiped the lenses of the powerful beacon which keeps all the fishing boats safe and sound.
And, once a year, Santa greets the lighthouse as he begins his trip around the world at midnight and wishes it goodnight just before dawn as he returns.
But it wasn't always that way.
Here is the story of one Christmas Eve when a lightkeeper and his family were responsible for - against all odds - saving Santa's Lighthouse.
